摘要:
A method, apparatus and system for signal modulation. A plurality of pixels are selected in a pattern such that a first pixel group of the plurality of pixels is unpaired with a second pixel group of the plurality of pixels throughout the pattern in a portion of a video signal. The intensity of the plurality of the pixels is altered at a constant magnitude in the portion of the video signal pursuant to the pattern in a substantially invisible way.

A system is disclosed that provides computer-aided processing of a rebate on a product. The system includes a rebate processing center communicating over a network with a manufacturer, a distributor, and a consumer. The rebate processing center maintains a promotion table and a transaction table in order to facilitate processing of product rebates and to offer the consumer a choice of disbursement options.

摘要:
A method for encoding a carrier signal in a video signal, the video signal having one or more frames, the frames each having a first field and a second field, the first field and the second field of each frame having a plurality of scan lines, each having a plurality of pixels with an intensity value indicating brightness, the method comprising selectively designating the plurality of scan lines of the first field of the one or more frames as up lines or down lines, calculating an optimum amount of adjustment to the pixels of the up lines and the down lines, and selectively increasing the intensity value of pixels of the up lines and decreasing the intensity value of pixels of the down lines by the optimum amount of adjustment thereby modulating the video signal with a carrier signal and creating a modulated video signal.

A magnetic inertial force generator includes a magnetic shell internally defining an armature chamber. At least two circumferential electric coils are spaced longitudinally within the chamber and mounted on a cylindrical inner surface of the outer shell. An armature centered by springs is reciprocably supported in the chamber and includes at least two axially spaced radially magnetized permanent magnets mounted on a longitudinally extending magnetic steel tube. The magnets extend in general alignment with the coils. Controlled energizing of the coils reciprocates the armature axially relative to the shell to develop an opposite inertia force on the shell for application to a connected body. The use of multiple radially magnetized magnets provides for improved performance and/or reduced cost.
摘要:
A method and apparatus is provided for adjusting a number of database replicas of a database based on a defined threshold value. The method comprises monitoring at least one operating condition associated with a database and accessing a prestored threshold value. The method further comprises comparing a value representative of the monitored operating condition with the prestored threshold value and adjusting a number of copies of at least a portion of the database based on the comparison.
摘要:
A vehicle powertrain control system including an electric motor drive system, a first battery coupled to the electric motor drive system, an electronically controlled switched coupled to the first battery, a second battery coupled to the electronically controlled switch, and where the electronically controlled switch applies power from the second battery to supplement the first battery.
